I'm going to go with a fourth option: Neutral Atheist (neither positive nor negative).
I don't believe in god, but I also don't assert that there is no god.
What I do assert is that a God that gives a flying **** about human beings cannot possibly exist.
The belief in God that is presented by humanity is an amazingly arrogant belief that makes absolutely no sense whatsoever when the sheer, mind-numbing scope of the universe and the utterly minuscule nature of the species as a whole.
The human-created version of God essentially treats humanity as the single most important thing in the universe. Logically, this makes no sense at all. Humans occupy an infinitesimally tiny fraction of the 3 dimensional space of the universe and have existed for an infinitesimally tiny fraction of the 4th dimension.
To put it into perspective, saying humanity is the most important thing in the universe is like saying the most important thing that has happened in all of the Earth's history was you eating a ham sandwich at lunchtime last Thursday. It takes something that is disproportionately minuscule and tries to extrapolate it's importance to a massive degree.
Ultimately, there may indeed be a supreme being that created the universe, but there is no logical reason to assume it gives a flying **** about any individual human, or even the species as a whole. Thus, regardless of the potential existence of said supreme being, there is no logical reason to believe in it in the absence of definitive proof of it's existence, because even if it DOES happen to exist, the end result will always be the same as if there was no such being: permanent annihilation and eternal non-existence upon death.
